The sound of being alive

Close your eyes for a moment. Even without seeing anything you can tell where you are. The human if a ceiling fan, birds chirping outside the window, distant traffic and someone laughing in another room or the rythem of your own breathing all paint a picture of the world around you. Hearing is more than the detecting sound...it is how we connect with people and experience emotions and navigate life.

The journey of sound beings with vibrations. When someone speaks or play a guitar or claps or they create waves that travel through the air. These waves enter the outer ear and travel down the ear canal until they reach the eardrum causing them to vibrate. Three of the smallest bones in the human bones- the hammer and the anvil and the stirrup amplify thesr vibratione before passing them into the cochleae, a spiral shaped organ filled with fluid.

Inside the cochleae are thousands of tiny hair cells. As the fluid moves these microscopic hairs bend and convert vibrations into electric signals. The auditory nerve carries these signals to the brain which identifies whether you are hearing a friend's caouce or a barking dog it gour favourite song.

One of the greatest gifts id hearing is language. Long before we learn to read or write we learn by listening. Babies recognise their mothers voice even before birth and children develop sepoech by hearing the sounds around them. Conversations allows us to share ideas and comfort another person and build relationships. Without hearing communication is still possible through sign language and other methods but spoken language has shapes human civilization for years.
